Let's divide 257937 by 51
We're looking to find how many times 51 goes into 257937.

Let's proceed to step 1:
51 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 51

Going ahead to step 2:
When dividing 25 by 51, we get 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 51

Advancing to step 3:
If we divide 257 by 51, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 255 from 257, we get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 51

On to step 4:
When dividing 29 by 51, we get 0 with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 50.0
If we subtract 0 from 29, we get 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 51

Step 5:
51 goes into 293 5 times with a remainder of 38.
Write down 5 as next digit of the result. 
Result so far: 505.0
If we subtract 255 from 293, we get 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 51

Advancing to step 6:
If we divide 387 by 51, we get 7 and a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 5057.0
If we take 357 away from 387, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
When dividing 300 by 51, we get 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 5057.5
If we subtract 255 from 300, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
450 divided by 51 is 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 5057.58
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
51 can be fit into 420 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 5057.588
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 5057.588 with a remainder of 0.0012.
